BACKGROUND The Ramapo River flows south and drains approximately 94 square miles within
southeastern New York State. Overall, 14 percent of the basin land use is identified as developed
with a concentrated area of development and impervious surface in the most upstream and
northernmost portion of the basin. Primary water quality concerns relate to waste water
discharges, nutrients, and stormwater runoff in the densely populated areas of the watershed.
In 2018, a Stream Assessment Survey was conducted by the Rotating Integrated Basin
Studies (RIBS) Program on the Ramapo River and tributaries (Figure 1). The RIBS Program
operates on a five-year, rotational schedule to generate statewide water quality data in support of
the Waterbody Inventory/Priority Waterbody List (WI/PWL) towards the goal of protection and
restoration of water quality resources (RIBS QAPP, 2018). The RIBS Program also conducts
special surveys outside of this five-year cycle to support Department-initiated priorities related to
water quality (RIBS QAPP, 2018). The objective of the Ramapo survey was to update condition
assessments for Waterbody Inventory/Priority Waterbody List (WI/PWL) segments 1501-0012,
1501-0036, and 1501-0037 and document potential impacts to the Ramapo River resulting from
two State Pollutant Discharge Elimination System (SPDES) permitted waste water treatment
facility (WWTF) (RAS QAPP, 2018).
Thirteen sampling locations (2 tributary, 2 WWTF outfalls, 9 mainstem Ramapo) were
selected to characterize the biological and chemical conditions within each WI/PWL segment of
the Ramapo River and to isolate potential impacts of point sources in the most upstream WI/PWL
segment (1501-0037). Two sampling locations were located in each WI/PWL segment for
condition assessments in both the downstream and middle WI/PWL segments (1501-0012 and
1501-0036, respectively), and nine sampling locations were distributed throughout the upstream
WI/PWL segment (1501-0037) where the WWTFs of interest are located (Table 1, Figure 1 and
Figure 2). The upstream WI/PWL locations, coupled with WWTF outfall sampling1 for Kiryas-Joel
(KJSTP-001) and Orange County Sewer District (OCSDSTP-001), were included to bracket
discharge outfalls for select WWTFs, and to characterize relative influence of those facilities on
water quality in the mainstem river. A reference site was also selected upstream of all selected
WWTFs for this evaluation to provide background condition information (Table 1, Figure 1 and
Figure 2). Additional WWTF discharge locations were identified throughout the watershed but not
selected for sampling. Locations are identified for reference (Table 1 and Figure 2).
To characterize the Ramapo River, the Bureau of Water Assessment and Management’s
Stream Monitoring and Assessment Section (SMAS) collected several measures of water quality
at each of the thirteen sampling locations between the months of July and October in 2018 (Table
1, Figure 1 and Figure 2). Measures of water quality included:
A) Water Chemistry and Stream Discharge
B) Benthic Macroinvertebrate Community
C) Stream Reach Physical Habitat Characteristics
D) Observer Ranking of Recreational Ability
1 OUTFALL SAMPLES WERE COLLECTED AT THE POINT OF DISCHARGE TO THE RECEIVING WATER

Section I: OVERVIEW
A) Water Chemistry and Stream Discharge
Methods used for water chemistry data collection are described by NYSDEC standard
operating procedures (SOP). The collection of water chemistry samples followed procedures
described in SOP #210-18 Collection of Water Column Samples for the Rotating Integrated Basin
Studies (RIBS) Program. Where the depth of water permitted, water chemistry samples were
collected using the depth-integrating suspended sediment sampler – wading (DH-81) method
(SOP #210-18, section 11.2). Where the depth of water was too shallow and when sampling
WWTF outfalls, water chemistry samples were collected using the direct grab method (SOP #210-
18, section 11.6). Water samples were processed using a contract lab with NYS Environmental
Laboratory Approval Program (ELAP) certification.
Stream discharge was measured using the velocity-area method according to Turnipseed
and Saur (2010). The velocity-area method (Midsection Method) calculates discharge by
subdividing a stream cross-section into 10 equally spaced stations and measuring depth and
velocity within each station and summing the products (Turnipseed and Saur, 2010). A top-set
wading rod and Sontek FlowTracker was used. Methods are described in detail in Turnipseed
and Sauer (2010) and Appendix I provides pertinent elements. Appendix II provides the field sheet
used in collection of stream depth and velocity for discharge calculations.
The collection of water chemistry samples and stream discharge included six sampling
events at all locations across a range of discharge conditions. Two sampling events (July 23,
2018 and October 1-2, 2018) were aimed at capturing the influence of a chicken processing facility
in Kiryas-Joel by sampling during planned plant shut-downs. Remaining sampling events were
conducted to document stream conditions at baseflow discharge. Ambient water chemistry
sampling included in situ and lab measured water quality analytes (Table 2). Chemistry results
were analyzed for exceedances of state water quality standards and summarized below using R
programing software (R Core Team, 2017). All raw chemistry results (in situ and lab reported)
with all applicable standards and exceedance determinations accompany this report as
Attachment I.
All Ramapo River survey data were subjected to the quality assurance/quality control
(QA/QC) protocols detailed in Appendix III. For water chemistry, an evaluation of the precision,
accuracy, and completeness of processed water chemistry samples after lab analyses were
performed following the methods detailed in part A of Appendix III of this report. Appendix III.B
includes a compilation of quality assurance results for each site. Only data meeting the highest
data quality standard are reported and used in this report (Appendix III).

Exceedances of Water Quality Standards
Exceedances of water quality standards occurred at every sampling location for several
of the analytes tested. A total of 30 lab-measured, and 6 in situ water quality analytes, were
analyzed at each of the 13 sampling locations. Out of the 1,444 lab-measured records and 396
in situ water quality records, there were 73 exceedances of established water quality standards
(6 NYCRR Part 703). There were exceedances in Aluminum (dissolved), Chloride, Copper
(dissolved), Dissolved Oxygen, Iron (total), Nitrite (expressed as Nitrogen), pH, and Total
Dissolved Solids. Nutrients are regulated by a narrative water quality standard stating: “None in
amounts that result in growths of algae, weeds, and slimes that will impair the waters for their
best usages” (6 NYCRR 703.2). There were instances of nutrient concentrations (Nitrate
(expressed as Nitrogen), Total Nitrogen, or Total Phosphorus) exceeding thresholds shown to
cause impacts to aquatic life (Smith et al. 2007; Smith and Tran 2010; Smith et al. 2013; Smith et
al. 2014). Exceedances varied in magnitude and were generally greater at sampling locations
closer to Kiryas-Joel and Orange County WWTFs.
Plots illustrating the range of analyte concentration values at each sampling location, in
river mile sequence from upstream to downstream, are included in this report (Figures 3 – 20).
Locations on a tributary are inserted between mainstem river mile locations. Analytes selected for
presentation were subset to those of specific interest to the study and those, as described above,
with exceedances of water quality standards and thresholds shown to impact aquatic life (Smith
et al. 2014). Therefore, the analytes presented here include: Aluminum (dissolved); Chloride;
Specific Conductance (in situ); Copper (total & dissolved); Dissolved Oxygen (in situ); Iron (total);
Lead (total); Nickel (dissolved); Nitrate, Nitrite, Total Nitrogen; pH (in situ); Sodium; Total
Phosphorus; Total Dissolved Solids; Zinc (total & dissolved). Site specific exceedances are
quantified in Section II.

B) Benthic Macroinvertebrate Community
Benthic macroinvertebrate communities were sampled to evaluate water quality impacts
to the aquatic life use. Where appropriate riffle habitat was present, collection of
macroinvertebrates was preformed using the kick method described in section 9.4 of SOP #208-
18 Biological Monitoring of Surface Waters in New York State. The two WWTF outfalls and one
mainstem Ramapo River site (RAMA-16.7), situated immediately downstream of a ponded area
in Mary Harriman Park, Harriman, NY, where excluded from collection of macroinvertebrates.
Replicate (n=4/site) macroinvertebrate samples were collected once at base flow
discharge at each sampled location. The contents of replicate kick samples for each site were
field-inspected to determine major groups of organisms present, and then preserved in alcohol
for lab inspection and identification of 100-specimen subsamples. Specimens were identified to
lowest possible taxonomic resolution, typically genus or species.
Biological assessments of water quality are generated from Biological Assessment Profile
(BAP) scores (SOP #208-18). BAP scores are calculated by taking the average of five normalized
10-scale community metrics and assigning that score to a four-tiered system of impact category
of non (7.5-10), slight (5.0-7.5), moderate (2.5-5.0), or severe (0-2.5) impacts (Figure 21). A final
BAP score below 5 suggests that the sampled stream is not achieving its aquatic life use goals
(Figure 21; SOP #208-18). A BAP score above 5 indicates that the sampled stream is attaining
its aquatic life use goals (Figure 21; SOP #208-18). Expected variability in the results of benthic
macroinvertebrate community samples is presented in Smith and Bode (2004).
On average, Biological Assessment Profile (BAP) scores ranged from moderately to
slightly impacted across all sites on the Ramapo River and tributaries (SOP #208-18; Figure 22).
The three locations in closest downstream proximity to Kiryas-Joel (RAMA_T2-3-0.2) and Orange
County WWTFs (RAMA-16.5, RAMA-16.1) were below the BAP impairment threshold (Figure 22).
The three most downstream sites in the watershed (RAMA-11.8, RAMA-4.8, RAMA-1.1) fell
above the impairment threshold (Figure 22). Ninety-five percent confidence intervals suggest
inconclusive results for RAMA-18.6 and RAMA-13.3 (Figure 22).

C) Stream Reach Physical Habitat Characteristics
Assessments of physical habitat conditions were performed by field crews at all sites
during macroinvertebrate collections following the methods detailed in section 9.10 of SOP #208-
18. The information collected in these assessments are used to calculate the Habitat Model
Affinity (HMA) (Table 3), an overall estimate of habitat quality which describes potential habitat
stress on aquatic life. The HMA is based on rankings of individual habitat characteristics on a
scale from 0 (poor) to 20 (optimal) which are then compared to a statewide reference condition
(Appendix IV). HMA scores are used to make final physical habitat assessments; Natural (80-
100), Altered (70 – 80), Moderate (60 – 70), and Severe (< 60). Results are described in terms of
percent similarity to the reference condition.
Habitat model affinity (HMA) scores and resulting final physical habitat assessments
ranged from natural to severe alteration across all sites (SOP #208-18; Table 3). Physical habitat
final assessments demonstrate that habitat was not a determining factor influencing benthic
communities at most sampling locations where macroinvertebrates were collected (Table 3);
natural (n=5), altered (n=3), moderate (n=1), severe (n=1). This was, in part, due to the extent of
undeveloped areas surrounding stream reaches near selected sites. Similarly, while many of the
sampling locations in the upstream WI/PWL segment (1501-0037) were situated in urbanized
areas, the physical habitat directly surrounding sampling locations is protected from development
due to land ownership; i.e. municipal and state property.

D) Observer Ranking of Recreational Ability
Perceptions of recreational ability were ranked at all sampling locations during each site
visit as per standard site visit protocols (SOP #208-18). The observer ranking of recreational
ability is a method of evaluating impacts to recreational use of a stream segment. Impacts to
recreational use have been correlated with “impairment of aquatic life use from nutrient
enrichment” and rankings below slightly impacted are indicative of significant impacts to
recreational ability (Smith et al. 2014). The ranking assesses primary (1°) and secondary (2°)
contact recreation, as well as a user’s desire to fish.
The first two questions of the recreational use evaluation describe the observers perceived
ability to participate in 1° and 2° contact recreation (Appendix V). Results of this ranking are the
primary gauge of whether the Ramapo River is achieving its designated recreational uses. Figure
22 illustrates the average observer ranking for desire to participate in 1° and 2° contact recreation
at each sampling location. Results of this survey suggest observers (NYSDEC field staff)
considered the desire to participate in 1° and 2° contact recreation to be slightly impacted at
sampling locations RAMA-13.3 south to RAMA 1.1, the Ramapo sampling location directly above
the pond in Mary Harriman Park, Harriman, NY (RAMA-16.8), and the upstream reference site
(RAMA-18.6). Sampling locations located in the upper WI/PWL segment (1501-0037), especially
those in proximity to WWTF, were largely considered impossible for 1° and 2° contact recreation.
Additional questions on a scale of 0-10 (0 – Best/Natural; 10 Worst/Severe) help
determine the factors influencing the user’s perception. Those factors are: 1) Water Clarity; 2)
Trash; 3) Periphyton; 4) Odor; 5) Discharge Pipes. Table 4 shows the mean recorded value for
these factors at each sampling location and Figure 23 shows the most commonly selected factors
reducing an observer’s desire to participate in 1° and 2° contact recreation. Other factors
described by observers were: 1) Low Dissolved Oxygen; 2) Proximity to Road; 3) Proximity to a
State Superfund Site; 4) Proximity to WWTF effluent discharge.

E) Sediment and Porewater Microtox® Analysis
Toxicity testing of surface waters, sediments, porewaters, and effluents are routinely
performed as part of the RIBS program (https://www.dec.ny.gov/chemical/29854.html). Sediment
toxicity was evaluated according to SOP #403-16 Microtox® Acute Toxicity Test for Sediments,
Porewaters and Effluents. Testing procedures use a bioassay to assess potential acute toxicity in
sediments and surface waters to aquatic life (SOP #403-16). Sediment and extracted sediment
porewater samples are tested using a bioluminescent bacterium Vibrio fischeri (V. fischeri). Tests
are a measure of light reduction between collected samples and a control following a 15-minute
exposure period and expressed as the median effect concentration (EC50) of a sample that
causes a 50% reduction in light emission from the V. fischeri. Appendix VI (Fact Sheet: Acute &
Chronic Toxicity Assessments of NY Streams & Rivers) describes toxicity testing procedures,
Assessment criteria and results classifications.
Porewater toxicity was found to be non-toxic at all sampled locations while sediment
toxicity ranged from non-toxic to severely toxic (Table 5). Sediment at the upstream reference
sampling location (RAMA-18.6) was non-toxic. Sediment at the sampling location on Tributary 25
immediately downstream of the Kiryas-Joel WWTF (RAMA_T25-0.2) was severely toxic (Table
5). Sediment at the two Ramapo River sampling locations immediately downstream of the Orange
County WWTF (RAMA-16.5, RAMA-16.1) was severely toxic (Table 5). Sediment at the most
downstream Ramapo River sampling location (RAMA-1.1) was slightly toxic (Table 5).

Appendix III: QA/QC Summary Report
A. QA/QC Analysis and Flagging of Non-Organic Water Chemistry Data
A.1. For non-organic water chemistry data sets, the designated staff performs quality assurance
quality control review using the BWAM QAQC R script. This script is maintained on GitHub
to preserve the revision history (https://github.com/BWAM/QAQC.git) and a locked version
is stored on the NYSDEC server in the BWAM folder on the L:Drive. The components of
the quality review are described below.
A.2. Laboratory QAQC. The BWAM QAQC R script checks that the laboratory analyses met all
internal QAQC checks by examining the laboratory applied qualifiers (see Fig.1). The
QAQC script assigns validator qualifiers to the data records if these criteria are met:
• Data accepted based on QAQC review (“A”)
• Rejected validator qualifier (“R”) is applied to all data with laboratory qualifiers B, N, *, D, or W
• Estimated validator qualifier (“J”) is applied to all data with laboratory qualifiers E or J
• Non-Detect validator qualifier (“U”) is applied to all data with laboratory qualifier U
NYS DEC Stream Assessment Survey – Data Report
Ramapo River 2018 Report 2019
Page 80 of 102
A.3. Accuracy Analysis. The BWAM QAQC R script checks that the spiked QA samples met
acceptable percent recovery criteria.
A.3.1. The sample matrix spike samples are used to document the bias of a method in a given
sample matrix. Matrix Spike Samples are collected at a percentage of sampling locations
specified in the QAPP and spiked in the analytic laboratory with a known concentration of
analyte. The samples are then analyzed to determine the accuracy (percent recovery) of
the analytic results for a given matrix. Spike samples are acceptable if the percent
recovery is 100% +/- the accuracy criteria specified in the QAPP. Otherwise, the spike
and its associated samples are flagged as rejected. Furthermore, if the sample is >4x the
spiked amount, the spike assessment is irrelevant and flagged NA.
A.3.2. The accuracy assessments are performed on a subset of samples. The errors discovered
with these QC assessments are applied to all regular ambient samples. This is done by
associating ambient samples to those QC samples closest in date/time to each sample.
A.3.3. The matrix spike duplicate samples are only analyzed when measuring organics.
A.4. Precision Analysis. The BWAM QAQC R script checks that the duplicate samples met
acceptable precision criteria.
A.4.1. Duplicate samples are analyzed from the same date/location to assess the method
precision. The relative % difference (%RPD) between these samples must satisfy
precision criteria as used by Ohio EPA (2018). Duplicate samples are rejected where
%RPD > (0.9465x^-0.344)100 +5
Where: x = sample / detection limit %RPD = [diff(duplicate pair)/av(duplicate pair)]*100
The precision assessments are performed on a subset of samples. The errors discovered with these QC assessments are applied to all regular ambient samples. This is done by associating normal samples to those QC samples closest in date/time to each sample. NOTE: the quantitation limit is NOT the method detection limit. Both are set by the lab and can vary week to week. The quantitation limit is the practical limit the lab was able to achieve and has confidence in on that date.
The complete Ohio EPA method can be found in Ohio EPA, 2018. Surface Water Field Sampling Manual. Appendix IV. https://epa.ohio.gov/Portals/35/documents/SW-Sampling-Manual-2018-AppIV.pdf.
A.5. Equipment Blank Analysis. The BWAM QAQC R script checks for contaminated equipment
blanks and based on the relative concentration of the ambient sample, determines whether
the level of contamination render the associated ambient sample results invalid.
A.5.1 An equipment blank is considered contaminated if the result value exceeds the
quantitation limit.
NYS DEC Stream Assessment Survey – Data Report
Ramapo River 2018 Report 2019
Page 81 of 102
A.5.2 If the equipment blank is contaminated, the results may still be useable depending on the
concentration in the ambient sample vs. the concentration in the equipment blank.
Acceptable thresholds are laid out in table 1 below. According to the Ohio EPA Surface
Water Field Sampling Manual (Ohio EPA 2018), the logic for these thresholds is as
follows:
“Laboratories often use a factor of three to differentiate a detected compound from background “noise” present in the system (analytical instrument, etc.). When a result exceeds three times the background noise, it is considered to be positively identified in the sample. We can consider blank contamination as extra “noise” in the system, since we don’t know the source of the contamination, and use this factor of three to help us assess our data. To do so, the sample concentration must be at least three times the blank concentration for us to be confident that analyte is truly present in the sample”
A.5.3 Table 1: Acceptable thresholds for equipment blank (EB) contamination
Sample Result Interpretation Validator Qualifier
Sample ≤ 3x EB Reject sample results in this range as insufficiently different from blank results
R
3x EB < Sample ≤ 5x EB Likely indication that the analyte is present but poor confidence in the numerical result - generally limit data use to data “trend” applications
T
5x EB < Sample ≤ 10x EB Consider the sample result to be an estimated concentration (qualified “J”) but still suitable for most data uses
J
< 10x EB Do not qualify data (blank contamination does not significantly change the result within the uncertainty of the value reported)
A.5.4 The equipment blanks are collected at a percentage of locations specified in the
QAPP. Contaminated equipment blank samples are applied to project sample results that
are nearest in date/time.
A.6. Parameter Pair Analysis. The BWAM QAQC R script flags data where component
parameters exceed total amounts.
A.6.1. The following component parameters should not exceed total parameters. Those that do
are rejected and the R validator qualifier is applied.

Nitrogen, Nitrite Nitrate+Nitrite as Nitrogen
Nitrate+Nitrite as Nitrogen Total Nitrogen
Nitrogen, ammonia (As N) Total Nitrogen
Nitrogen, Kjeldahl, Total Total Nitrogen
Orthophosphate as Phosphorus, Dissolved Total Phosphorus
A.7. Holding Time Analysis. The BWAM QAQC R script calculates the holding time for each
sample and flags those samples that exceed established holding times.
A.7.1. The holding time thresholds are published in Standard Methods for the Examination of
Water and Wastewater (2017). Data are rejected and an “R” validator qualifier is applied
if the holding time threshold +12 hour buffer is exceeded.
A.7.2. The holding times for Nitrate samples are ignored because this parameter is not
calculated from TKN and Ammonia samples and is not measured directly.

A.8. Summary of Internal Data Flags. Depending on application of the data and data quality
objectives of a survey, increasingly stringent requirements may be placed on the data. The
following validator qualifiers are applied to the data records according to the procedures
described above. 2
